WACOOL 3L 3Liter 100oz BPA Free EVA Hydration Pack Bladder, Leak-Proof Water Reservoir

I thought mine was a good deal: A water bladder with a cleaning kit for $23. It may not be the best in the world, but if you’re looking for something that works and don’t mind if you lost it either, this is a good choice. Mine didn’t leak at all and the hose worked.-The bladder material is made of lightweight but tough rubber. I don’t think it’d puncture that easily.-The inside has a very smooth, glass-like feel. I think it’d clean easily.-Their customer service is AMAZING. Great people.Note:-There is a plastic ring where the hose and the mouthpiece meet that slides up and down to lock/unlock water flow. It’s a bit stubborn at first, but move it a few times and it loosens up. It’s not broken. And you have to bite the nozzle to get water flow.-Be aware that the top is open and folded over, and secured by a plastic clip. ***Be sure to slide the white core piece of the clip IN BETWEEN the fold, or it’ll slip off and water will be everywhere (you’ll see when you get it and find out why I say this). It’s good that the top is open for extremely easy cleaning (better than trying to brush through the fill cap), but it is another opening and that may be an issue for some people. But so far, it doesn’t leak around the fold and the clip holds the entire weight w/o slipping off.I had doubts about the open top design, but it works. If anything, it has the benefit of being able to stick your whole hand in it for complete cleaning. I’m actually thinking about getting another one as a spare.
